Was bedeutet der Fehlercode?

The engine control module (ECM) compares the signal from the front catalytic converter temperature sensor with a calculated value. If the temperature rises too quickly after start-up, the code is set. The cause may be poor contact, an open circuit or short circuit in the wiring, or a damaged temperature sensor.

Mögliche Ursachen

Play, contact resistance or oxidation in the connections to the front sensor
Open circuit or short circuit in the wiring to the sensor
Damaged temperature sensor

Was Sie tun können

1Read and clear the fault code and check whether it returns
2Check the connector at the front catalytic converter temperature sensor for play, contact resistance and oxidation
3Check the wiring to the sensor for open circuit and short circuit
4Use a multimeter to check that the supply to the sensor has no open circuit or short circuit
5If you have a diagnostic tool, read the sensor temperature in live data during warm-up and see whether it rises steadily
6Have a workshop replace the temperature sensor if the fault remains
